Add support for dependency groups

[tofay]

By making BundleCommand inherit from poetry's GroupCommand, and passing the detected groups through to the venv bundler.

Fixes #8

Hey!

I need this SO BADLY and would be awesome if the PR were accepted.
Any chances? :D

Thanks for the great work

Hello - ➕ this solves a blocking problem for my project. Curious if this is a change you're open to accepting? Thanks!

This looks really helpful!
@neersighted would it be possible to ping the reviewers, would be a shame if that PR goes to waste :)

Sorry for the late feedback. Overall this looks good to me. Can you add some simple tests with the different options in tests/console/commands/bundle/test_venv.py, please?

[tofay]

I've added the tests as requested.
